BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a three-dimensional (3D) scan system using 3D modeling
technology, which is capable of measuring and analyzing the shape, weight and composition
of a human body using a photographing unit and allowing checking of health-related
conditions or acquiring a variety of health information and human body measurement
information using analysis results, and an information provision method using the
system.
2. Description of the Related Art
[0002] 3D modeling technology can extract 3D data through actual photographing, unlike existing
object scanning technology.
[0003] Hitherto, there have been cases where body photos, such as simple full-length photos
or facial photos, are captured and used for medical and clothing purposes. However,
these cases are disadvantageous in that it is difficult to implement 3D shape models
because they chiefly use frontal photos.
[0004] Conventional technology for capturing the shape of an object and/or a human includes
a method of scanning shape information using an active sensor based on laser or pattern
light and extracting the texture of scanned meshes from captured color images. This
method is chiefly limited to static objects, and is used for the creation of high-quality
models. However, this method has disadvantages in that the restoration of a static
object requires an excessively long period of time and the restoration of a dynamic
object does not guarantee the restoration of a real 3D image.
[0005] Meanwhile, although many apparatuses for analyzing body composition have been disclosed,
a variety of visual data is not effectively represented so that it can be viewed at
a glance, with the result that the length of the period required for the analysis
and the accuracy of the analysis are limited.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] Preferred embodiments of the present invention will be described in detail below
with reference to the following drawings.
[0022] FIG. 1 is a diagram showing the hardware construction of a scan system according
to the present invention, FIG. 2 is a block diagram showing the construction of the
scan system according to the present invention, FIG. 3 is a diagram showing the software

[0023] A 3D image scan apparatus 200 is an apparatus that can be used both in the 3D simulation
modeling field for which data about multiview images of a human body and/or an object
captured by digital cameras is three-dimensionally converted and used for purposes
related to plastic surgery, obesity clinics, health, clothing, shoes, hats and caps,
mock-ups, the measurement of dimensions of cultural assets, sculptures, reliefs, medals,
trophies, special clothing, gas masks, helmets, glasses, underwear, brassieres and
security systems and in the health industry field for which abdominal fat rate, skeletal
muscles and basal metabolic amount are analyzed through the measurement of a human
body and body weight and the analysis of body composition and then prescriptions are
offered.
[0024] Here, the engine unit of the software of the scan apparatus converts data measured
through the simultaneous photographing of a plurality of digital cameras, that is,
a photographing unit 210, into 3D information, and utilizes data acquired by a weight
scale for measuring body weight and a body composition analyzer for performing body
composition analysis, as follows:
[0025] First, the data can be used for the measurement of a human body.
[0026] In this case, it is possible to measure every portion of a human body. This information
is used in the capacity of information regarding the health of a human body, for example,
to assess bending or vertical symmetry. The contour lines of the surface of a human
body are used for the analysis of the height or symmetry of a human body or plastic
surgery simulation, and are also used for fashion simulation (for example, for clothing,
shoes and headgear). Particularly, with regard to plastic surgery, the enlarged or
reduced shape of a desired portion of each region of a human body, such as the face,
the breast, the abdomen, the inner part of the thigh, the buttocks, and the forearm,
is simulated on a 3D screen in real time.
[0027] The weight scale measures the weight of a human body, and the body composition analyzer
analyzes various types of body composition, such as the body water, protein, inorganic
matter, body fat, muscle mass, body fat amount, body fat rate and abdominal obesity
of a human body. On the basis of data about the measurement and the analysis, an exercise
prescription and a dietary prescription are offered.
[0028] Referring to FIGS. 1 to 3, the 3D image scan apparatus 200 having the above-described
construction according to the present invention and a 3D image scan system 100 using
the 3D image scan apparatus will be described below.
[0029] In this case, it is preferred that the outside housing of the scan apparatus 200
be formed of Fiberglass Reinforced Plastic (FRP) or aluminum. However, it will be
apparent that the material of the outside housing is not limited thereto and any type
of industrially usable plastic and metal may be used as the material of the outside
housing.
[0030] As shown in the drawings, the apparatus 200 includes at least one photographing unit
210 configured to include a plurality of digital cameras and a hub and send images,
captured by the digital cameras, to the Personal Computer (PC) of an integrated controller
through the hub, a weight scale 220 configured to measure the body weight of a subject
of measurement, and a body composition analyzer 230 configured to measure the body
composition of a subject of measurement.
[0031] That is, in order to measure the human body and/or body composition characteristics
of a subject of measurement 150, the photographing unit 210 including digital cameras
is installed on a wall or a ceiling inside the scan apparatus 200. In this case, it
is preferred that there be 8 to 16 cameras. In order to enhance precision, a larger
number of cameras may be installed when necessary.
[0032] The photographing unit 210 generally includes the digital cameras and the hub 215,
and performs a function of sending images, captured by the digital cameras, to the
PC of the integrated controller 310 through the hub 215.
[0033] The photographing unit 210 according to the present invention can acquire 3D modeling
data using a plurality of general digital cameras, rather than special cameras. Consequently,
there are advantages in that the fabrication of the apparatus and the photographing
of images can be facilitated, color photo data can be acquired in real time, and the
simulation of the plastic surgery of a desired portion of a human body can be promptly
performed using such 3D data.
[0034] However, it will be apparent that the photographing unit is not limited to the digital
cameras, but that a variety of cameras can be used.
[0035] A method of modeling a 3D human body or object according to the present invention
which is performed after the human body or object has been photographed using the
photographing unit will be described below.
[0036] The present invention utilizes multiview image information capable of restoring the
3D shape of an object using the silhouettes and color information of multiview images
captured using multiview cameras as a way of capturing shape information from various
view points using passive cameras and then restoring the shape and surface color information
of an object on the basis of the acquired image information.
[0037] In this case, it should be possible to restore a 3D shape model including the geometrical
shape and intrinsic surface color texture information of an object and/or a human
using the silhouette and color information of multiview images.
[0038] Furthermore, this method includes the step of extracting texture coordinates from
the results of enlargement of a predetermined central area in a predetermined ratio
using the coordinates of a deformed standard model and the results of reduction of
a peripheral area in the same ratio with respect to the front image and at least one
side image of the face and converting deformed model coordinates into pixel coordinates,
and the step of storing the front and side images using the texture coordinates for
respective polygons determined by the pixel coordinates and determining the stored
results to be deformed textures. In this case, the central area is an area set in
the face and around the eyes by a user and the peripheral area is the overall area
with the central area of the face excluded.
[0039] Accordingly, this method has the advantages of not requiring software or hardware
compression and not requiring restoration parts, unlike the conventional technology,
creating an excellent texture even using front and side images captured under slightly
different illumination conditions, naturally processing the boundaries between polygons,
and creating an excellent texture using limited resources, compared to the conventional
technology, thus resulting in the creation of a clearer 3D model.
[0040] A preferred 3D modeling method thereof is configured as described below.
[0041] This method includes the step of receive multiview images obtained by photographing
an object from a variety of viewpoints in voxel space composed of voxels of regular
size in 3D space including the object and extracting silhouette and color information
therefrom, the step of constructing a visual hull through silhouette intersection
using the silhouette information, the step of approximating polygons on the section
of the visual hull to the intrinsic geometrical shape of the object using the color
information while moving along the section, the step of connecting the approximated
polygons into a mesh structure and representing the 3D geometrical shape of the object,
the step of extracting the color texture of the surface of the object by projecting
each mesh structure onto the multiview images, and the step of creating a 3D shape
model by modeling the intrinsic shape and surface color information of the object
composed of the mesh structure and the color texture corresponding to the mesh structure.
[0042] According to this method, when the shape information of a 3D object is restored,
it can be expected that the restoration quality of the graph-cut method having restoration
accuracy equal to that of a laser scanner can be achieved within the restoration period
of the silhouette intersection method that is chiefly used to restore the shape of
a dynamic entity.
[0043] The restoration of a 3D shape model is performed in 3D space including an object.
Respective multiview images of the 3D model have been previously calibrated with respect
to the world coordinate system of voxel space. Each image is divided into a foreground
including the object and a background.
[0044] When an image input unit receives multiview images and transmits the received images
to a silhouette and color extraction unit, the silhouette and color extraction unit
extracts a silhouette map representing a projected portion of an object to be restored
and a color map from the multiview images, and a visual hull restoration unit restores
the visual hull in voxel space through silhouette intersection using the extracted
silhouette map.
[0045] Thereafter, after the polygon approximation process is performed, a mesh structure
creation unit creates the overall mesh structure by connecting the polygons of respective
sections to each other.
[0046] A color texture map having a mesh structure is created by projecting the shape information
of an object represented in the mesh structure onto the multiview images, and a 3D
shape model creation unit creates a 3D shape model by modeling the intrinsic shape
information of the object composed of the mesh structure and the color texture map
corresponding to the mesh structure.
[0047] A section of the visual hull is composed of linear polygons in which area contour
lines are continued, the shape of the actual object is included within the polygons,
and corresponding points, such as colored corresponding lines 150, 151 and 152, can
be obtained along polygon lines obtained by projecting respective polygon segments
onto the multiview images.
[0048] The 3D shape represented in the overall mesh structure created by the polygon approximation
process is
characterized in that it is projected onto all pixels corresponding to an object silhouette area when projected
onto the multiview images, and the edge between adjacent meshes of the mesh structure
is
characterized in that it is developed along the color edge component of the surface of the object. That
is, as shown in FIG. 13, the shape of an object is desirably represented and the silhouette
maps of respective images are all satisfied.
[0049] Next, the constructions of the weight scale and the body composition analyzer will
be described.
[0050] The weight scale 220 for measuring a subject of measurement 150 is provided on the
bottom of the scan apparatus 200 on which the subject of measurement 150 is located,
and the body composition analyzer 230 for measuring body composition is connected
to a system control unit 320 and an external PC 331 and sends measured data.
[0051] Accordingly, the body weight and body composition of the subject of measurement 150
can be simultaneously measured and/or analyzed at the same location, so that customized
exercise and dietary prescriptions can be presented based on a variety of types of
body composition analysis data, such as data about the body water, protein, inorganic
matter, body fat, muscle mass, amount of body fat, body fat rate, abdominal obesity
of a human body.
[0052] The body composition analyzer 230 generally uses a bioelectrical impedance method.
The body composition analyzer 230 includes a plurality of electrodes configured to
come into contact with the hands of the subject of measurement 150 and input and output
means configured to include an input unit for inputting information about the subject
of measurement 150, such as gender, age and human body measurement data, and a display
unit for displaying measured states and measurement results.
[0053] In this case, in order to increase the accuracy and diversity of examination, it
is preferable to attach a sensor 235 onto the top of the weight scale 220 on which
the feet of the subject of measurement 150 are located and obtain data through the
hands and feet of the subject of measurement 150.
[0054] Furthermore, a plurality of illuminators 250 for aiding taking of photos is installed
on a wall or a ceiling, in which case the plurality of illuminators 250 is connected
to an illumination controller 255.
[0055] A speaker 260 is communication means by which an operator at an operating desk 330
outside the scan apparatus transmits information and instructions to the subject of
measurement 150 through an operator microphone 332.
[0056] Meanwhile, an internal monitor 240 is installed inside the scan apparatus 200 so
that the subject of measurement 150 can monitor all types of status, and a CAM 280
may be installed inside the scan apparatus 200 so that the operator outside the scan
apparatus 200 can easily view the location and motion of the subject of measurement
150 from the outside.

measuring and illumination apparatuses is provided.

maintaining the scan system 100 and controls the photographing unit 210, the weight
scale 220, the body composition analyzer 230, the internal monitor 240, the illuminators
250, the speaker 260 and the microphone 270 through the PC 331.
[0059] The system control unit 320 includes a camera control unit 321 for controlling the
calibration and photographing of the photographing unit 210; a human body measuring
unit 322 for performing 3D modeling using a measuring technique based on contour lines,
colors and squares; a body composition analysis unit 323 for analyzing body composition
and offering prescriptions on the basis of data measured by the body composition analyzer
230; a body weight analysis unit 324 for analyzing and managing body weight on the
basis of data measured by the weight scale 220; a monitor control unit 325 for controlling
the internal monitor 240; and a voice communication unit 326 for managing the speaker
260 and the microphone 270.
[0060] The internal monitor 240 is provided for the subject of measurement 150 located inside
the scan apparatus 200, and the speaker 260 and microphone 270 for providing information
about the status of progress and the correction of a position is used to support communication
between the subject of measurement inside the scan apparatus 200 and the operator.
Meanwhile, it is preferable to use a camera SDK so as to control the cameras.
[0061] The human body measurement system according to the present invention used in the
method of measuring a human body will be described below.
[0062] The integrated controller 310 is further provided to analyze and store data captured
and measured inside the scan apparatus 200 and images, body weight data and body composition
data acquired through the system control unit 320. The integrated controller 310 includes
an integrated control process 311 for storing a program in charge of integrated control

unit, analyze corresponding body composition, and send analysis result data to the
operator PC through an interface.
[0065] An operating desk 330 is provided outside the scan apparatus 200 to connect to the
integrated controller 310 over a network and remotely manage and operate the photographing
unit 210 and the measuring devices 220 and 230. It is preferred that the operating

lower parts of a human body, the outside and inside lengths of the arms, and the height
of a subject of measurement attributable to the opening of the legs based on the lengths
of the right and left feet and measure any portions of a human body as well as the
shoulder, the head, the neck, the upper arm, the breast, the waist, the buttocks,
the inner part of the thigh and the calf of the leg.
[0086] In the field of plastic surgery, it is preferable to enable the insertion of a prosthesis
into a 3D shape by using a database or freely designating a volume, the change of
a 3D shape by using a mouse and a touch screen, and the removal of a specific portion
of a 3D shape using zooming in and out, cc designation and free cutting.
[0087] In the analysis of body composition, for the whole body, intracellular fluid, extracellular
fluid, protein, inorganic matter and body fat are used, and for body portions, (the
trunk, the left arm, the right arm, the left leg and the right leg) x body fat, body
water and muscle mass is used. In the measurement of the body weight, it is preferable
to separately measure and analyze left and right body weights using left and right
body weight analysis and 3D modeling techniques. In this case, it is more preferable
to perform implementation so as to maintain a body weight accuracy of +/- 50g.
[0088] In order to compensate for the analysis of body composition data, the body weight,
the muscle mass, the amount of body fat, the body fat rate and the extracellular fluid
ratio are considered and analyzed for the muscle and body fat balance, the correlation
between the body weight, the body fat, the abdominal fat rate and muscle is considered
and analyzed for the assessment of the bodily shape, the abdominal fat rate, the hypodermic
fat area, the visceral fat area, the abdominal fat area and VSR are considered and
analyzed for the analysis of abdominal obesity, BMI, WHI, WHR, BMR, Kcal and the extracellular
fluid ratio are considered and analyzed for the provision of reference values, and
the body water, protein, inorganic matter and body fat (represented in a Pie chart)
are considered and analyzed for the analysis of body composition.

part are entered.
[0099] In this case, the comparison with a standard bodily shape may be overlaid on the
3D area of section 1 or separately indicated, should be automatically measured, and
should be able to correct a portion of measurement. Furthermore, a consultation section
regarding the assessment of the bodily shape is set in the lower portion of the screen.
[0100] Next, referring to FIG. 9, a simulation input screen 440 used to enter values for
plastic surgery will be described.
[0101] First, on a side of the upper portion of the screen, a target portion for plastic
surgery can be selected from among the breast, the abdomen, the inner part of the
thigh, the buttocks and the forearm. In this case, when an item is selected, the location
of section 1 is indicated, the corresponding item is indicated in a portion below
the upper portion, and a balloon effect and a reduction and enlargement function using
a mouse may be added. Furthermore, shapes regarding plastic surgery are divided into
a shape before surgery and a shape after surgery, and the results of the plastic surgery
will be shown three-dimensionally.

method is selected by selecting No. 1 or No. 2, a model (prostheses of 5cc size) is
presented, and a prosthesis model and the location of insertion of a prosthesis are
allowed to be selected, or the selection may be freely performed by a user.
[0103] In a plastic surgery simulation related to the abdomen, the inner part of the thigh,
the buttocks or the forearm, a standard model is presented and allowed to be selected,
the amount of fat to be removed is allowed to be entered, and a desired shape is allowed
to be adjusted by a customer. In this case, it is preferable to configure a screen
so that a separate consultation section is provided in the lower portion of the screen,
thereby facilitating management.
[0104] As shown in FIG. 10, the data and graph regarding the analysis of the body composition
analysis of the subject of measurement 150, data about muscle and body fat balance,
a bodily shape assessment item, the analysis of abdominal obesity, right and left
balance and the muscle mass for each body portion are indicated on a human body measurement
screen 450 for displaying the measured values of a human body. A consultation section
is provided in the lower portion of the screen to allow comparison with previously
measured values.
[0105] As shown in FIG. 11, in an exercise prescription screen 460, the body weight, the
body fat and the muscle mass are indicated, a corresponding exercise prescription
is presented, and information about a recommended exercise menu, an aerobics menu,
a muscle exercise menu and auxiliary food is provided in a customized manner. A consultation
section is provided in the lower portion of the screen to allow comparison with previously
measured values.
[0106] As shown in FIG. 12, a three major nutrient prescription, a food menu and a menu
table are provided in a dietary prescription screen 470 in a customized manner. A
consultation section is provided in the lower portion of the screen to allow comparison
with previously measured values.
[0107] It will be apparent that the above-described basic output screens (FIGS. 6 to 12)
are merely examples and the output screens may be configured in different manners.
[0108] As described above, according to the scan system of the present invention, the photographing
unit is constructed of a plurality of general digital cameras, the digital cameras
are installed at various angles inside the scan apparatus and operated to capture
photos at the same time, and 3D data can be extracted using multiview images, so that
there are advantages in that processing speed is increased and a variety of types
of 3D modeling editing can be performed.
[0109] Furthermore, the measurement of the body composition and human body of a subject
of measurement can be performed at the same time, so that the uncertainty of data
provided by a subject of measurement can be eliminated, thereby improving the accuracy
of measurement and analysis results, and photographing and measurement can be performed
at the same location, so that the measurement of a human body and the analysis of
body composition can be performed conveniently and rapidly, thereby facilitating multipurpose
use.
